GAGE.

Specification of Letters Patent. Application filed March 1, 1913.

Patented Jan. 27, 1914. Serial No. 751,588.

To all whom it may concern Be it known that I, GEORGE R. LEE, a citizen of the United States, residing at Ashton, in the county of Spink and State of South Dakota, have invented certain new and useful Improvements in Gages, of which the following is a specification, reference being bad therein to the accompanying drawing.

This invention relates to gages to be used in boring holes straight through timber, and has for its object the production of an effi cient gage whereby the auger bit will be so guided as to keep the same in the central posit-ion to prevent the auger from boring out of its correct line.

Another object of this invention is the production of a simple and eflicient gage which may be adjusted to different sizes of timber and may, at the same time, be sufficiently held on the timber.

With these and other objects in view, the invention consists in general of certain combinations and arrangements of parts, as will be hereinafter described, illustrated in the accompanying drawings, and specifically claimed.

In the drawings, Figure 1 is a perspective of the clamp and-gage. Fig. 2 is a central longitudinal section thereof. Fig. 3 is a section taken on line 3-3 of Fig. 2. Fig. 4 is a section taken on line 4-4 of Fig. 2. Fig. 5 is a vertical section taken through the auger guide. Fig. 6 is a section View of the modified form of the invention wherein a round stem is used for adjusting the timber gripping section of the clamp or gage.

By referring to the drawings, it will be seen that the present invention consists of an auxiliary gage section 1 and aprimary gage section 2. The auxiliary section 1 is preferably square, and fits in the socket 3 formed in the primary section. This socket 3 passes the entire length of the primary section 2 and constitutes a means for bold ing the auxiliary section 1 of the gage. The primary section of the gage is provided at its inner end with a pair of diverging arms 5, which arms carry at their upper ends adjusting screws 6. These screws 6 are adapted comprises a hollow to engage the timber for firmly holding the timber upon the gage.

An adjusting clamp member 7 is slidably mounted upon the primary section 2 and body 8 which carries an upwardly extending integral member 9. The integral member 9 is provided with an adjusting screw 10 at its upper end for gripping the end of a piece of timber for holding the gage in firm engagement with the timber.

An auger guide 11 is carried by one end of the auxiliary section 1 and is provided with a socket portion 12 through which the auger passes. A spindle 13 the upper ends 14: of the auger guide 11 and this spindle is adapted to hold the bit which forms the hole in the piece of timber to be bored.

As illustrated in Fig. 6, the auxiliary portion 1 may be formed round to fit in the primary section 2 and a key 3 may be employed to hold the cylindrical portion 1 against rotation relative to the primary section.

From the foregoing description it will be seen that a very efiicient gage clamp has been produced for holding material to be bored firmly upon the gage so as to prevent the auger from getting ofi' the center, and by use of the present device it will be seen that the material by being firmly clamped may be easily handled for boring.

The clamp 7 is adjustably held upon the primary section 2 by means of an adjusting screw 7 Having thus described the invention, what is claimed as new, is

A gage comprising a primary member provided with a rectangular longitudinally extending opening, arms extending above one end of said primary member, set-screws passing through said arms, a collar surrounding said primary member and slidably mounted thereon, means for holding said collar in an adjusted position upon said primary member, an arm extending above said collar and positioned in alinement with the longitudinal center of said primary member, a set screw passing throughsaid last mentioned arm, a rectangular auxiliary passes through V member slidably mounted in the longitudi- In testimony whereof I hereunto afiix my nally extending openilg of bsaid primary signature in presence of two Witnesses. member, a uide exten ing a ove the outer 1 end POI'tiOIT of said auxiliary member and GEORGE positioned in alinement with the arm of said Witnesses:
